Hello there!
I am a Masters student working at EPFL with Empatica E4. For the moment, as both the device and the data from it are very new to me, I am testing the solidity of the signals.
At first look, the EDA signal looks very noisy and filtering with Ledalab doesn't seem to solve the problem. However, as I said I don't have experience in processing EDA signals, so I would like to know if anyone can help me going through the basic and most common and efficacious processing steps. Any suggestion is highly appreciated!
Thank you in advance to anyone whose willing to help!
Hi Luca;
I would be happy if you could share with me your experience. Luca Merolla
Hello Mahsa!
Unfortunately, I don't have much experience to share. As of now, I chose to filter the signal with a moving median and look at the tendency by calculating the upper envelope and the area under the curve. Though this applies specifically to my signal, which seems to be a little too flat than expected.
For all I know, there is no ground truth when dealing with autonomic signals, so you really have to look at you data and identify the kind of analyses that best explain it.
Maybe this paper can help you getting to know EDA and some analysis strategies available: Article Innovations in Electrodermal Activity Data Collection and Si...
Good luck!
Luca
